Title: Additive for coal/water slurry
Inventor: TAGUCHI JIYUN
IPC: C10L1/32
Filed: 1983-12-01
Abstract: PURPOSE:To provide an additive for a coal/water slurry contg. humic acid or salt thereof, which has excellent viscosity reducing and slurry stabilizing effects and generates no sulfur oxide when burned. CONSTITUTION:The additive contains humic acid or salt thereof. Humic acid is an amorphous acidic organic substance in brown to black color present in soil or coal with a low rank of coalification, which is soluble in alkali but is insol. in acid. It is obtained, e.g., by treating soil or coal with water, organic solvent or nitric acid to remove foreign matters, extracting it with dilute alkali and adding inorganic acid to the extract until it becomes acidic. Preferred salts are alkali metal salt and 1-4C alkyl amine salt. Use of a nonionic surfactant of the formula in combination with humic acid or salt thereof improves viscosity reducing effect and stability of a slurry with a reduced amt. of the additive.
